The image of the "Tank Man" is lodged in our collective memories of the Beijing student uprising of 1989, but there many don't recall the events spanned over a month.

In April 1989 students in Beijing began to rally against the government in what was known as the 1989 Democracy Movement after the death of Communist Party General Secretary, Hu Yaobang, who was seen as a reformer.

On June 4, 1989, after a month and a half of protests, the government cracked down on the protestors in Beijing's Tianamen square, killing hundreds of civilians in what became known at the June Fourth Incident.

Here is a look back at the events in 1989.
